David McCandless turns complex data sets like worldwide military spending, media buzz, Facebook status updates and more into beautiful yet simple diagrams. He proposes information design as the tool we use to navigate today's information glut, finding unique patterns and connections that may just change the way we see the world.
By now, we're used to letting Facebook and Twitter capture our social lives on the web -- building a "social layer" on top of the real world. At TEDxBoston, Seth Priebatsch looks at the next layer in progress: the "game layer," a pervasive net of behavior-steering game dynamics that will reshape education and commerce.
Jamil Abu-Wardeh jump-started the comedy scene in the Arab world by founding the Axis of Evil Comedy Tour, which brings standup comedians to laughing audiences all over the Middle East. He's found that, by avoiding the "three B's" (blue material, beliefs and "bolitics"), the Axis of Evil comics find plenty of cross-border laughs.
A founding member of the Axis of Evil Comedy Tour, standup comic Maz Jobrani riffs on the challenges and conflicts of being Iranian-American -- "like, part of me thinks I should have a nuclear program; the other part thinks I can't be trusted ..."
Having explained the science behind global warming, and addressed the arguments of the climate change sceptics earlier in the series, in this third and final part Dr Iain Stewart looks at the biggest challenge now facing climate scientists. Just how can they predict exactly what changes global warming will bring? It's a journey that takes him from early attempts to model the climate system with dishpans, to supercomputers, and to the frontline of climate research today: Greenland. Most worryingly, he discovers that scientists are becoming increasingly concerned that their models are actually underestimating the speed of changes already under way.
Dr Iain Stewart investigates the counter-attack launched by global warming sceptics in the 1990s. At the start of the 1990s it seemed the world was united. At the Rio Earth Summit the world signed up to a programme of action to start tackling climate change. Even George Bush was there. But the consensus didn't last. Iain examines the scientific arguments that developed as the global warming sceptics took on the climate change consensus. The sceptics attacked almost everything that scientists held to be true. They argued that the planet wasn't warming up, that even if it was it was nothing unusual, and certainly whatever was happening to the climate was nothing to do with human emissions of greenhouse gases.
After he swam the North Pole, Lewis Pugh vowed never to take another cold-water dip. Then he heard of Lake Imja in the Himalayas, created by recent glacial melting, and Lake Pumori, a body of water at an altitude of 5300 m on Everest -- and so began a journey that would teach him a radical new way to approach swimming and think about climate change.
Sheryl WuDunn's book "Half the Sky" investigates the oppression of women globally. Her stories shock. Only when women in developing countries have equal access to education and economic opportunity will we be using all our human resources.
